I beam.....im just doing a modified rebuild and I don't see any hp gains of 500+! nowadays to recondition my rods will cost me $150......new rods $250-300.! crank regrind is 150.....new cast crank....$300/350.!!! it's a 1970 340 thats currently 100% stock.....considering a cast new crank but the stock forged unit is fine. I'm kinda stumped on that decision too!
